Answer:
D, x = (ln(0.5) - 1)/2
Step-by-step explanation:
8e^(2x+1) = 4
e^(2x+1) = 0.5
2x+1 = ln(0.5)
2x = ln(0.5) - 1
x = (ln(0.5) - 1)/2
A car travels - 1/6.
in 3/5 of an hour -
60 / 5 - 12 x 3 = 36.
so in 36 minutes.
4/5 = 36+12 = 48 minutes.
2/6.
5/5 (full hour ) = 60 minutes.
3/6.
Car can travel - 3/6.
Answer:
b = 10
Explanation:
Lets start by combining like terms (b):
3/2b + 1/5b
to combine these fractions you must get them to both have the same denominator:
3/2 · 5/5 = 15/10 multiply top and bottom by other fractions denominator
1/5 · 2/2 = 2/10 multiply top and bottom by other fractions denominator
15/10 + 2/10 = 17/10
17/10b = 17
Now we want to get the b to be by itself, so lets first multiply both sides by 10:
17b = 170
Now lets divide both sides by 17:
b = 10

Answer:
$6.96
Step-by-step explanation:
(4*8.99) + (3*7)
35.96 + 21 = 56.96
50- 56.96 = -6.96 So she owes 6.96
Answer:
1, 0.06, 0, and 0.22
Step-by-step explanation:
Probability can't be negative or more than 1.
Therefore, 1, 0.06, 0, and 0.22 are all possible probabilities.
